ich bitte euch noch mals um Hilfe
Ich möchte in einem Latex Dokument ein Bild einfügen ausdem ich Ausschnitte vergrössert innerhalb des bildes Darstellen möchte.
Hier zu habe ich auch im Netz eine Vorlage gefunden.
Aber ich komme nicht sorecht klar damit da ich bis jetzt durch Probieren nicht raus bekommen wie ich das Steuern kann das Die ausschnitts Fenster da sind wo ich Sie haben möcht und in der Grösse wie ich sie brauche und auch die Grösse der Ausschnitte bestimmen kann.
Es wäre auch gut zu wissen wie ich das einstellen muss wenn man mehrere Bilder so einfügen will das die Ausschnittsbereiche individuell je Bild einstellen kann.
Danke
Hier das Beispiel
